2009-04-17USB: fix oops in cdc-wdm in case of malformed descriptorsOliver Neukum

2009-04-14cdc-acm: Fix long standing abuse of tty->low_latencyAlan Cox
ACM sets the low latency flag but calls the flip buffer routines from IRQ context which isn't permitted (and as of 2.6.29 causes a warning hence this one was caught) Fortunatelt ACM doesn't need to set this flag in the first place as it only set it to work around problems in ancient (pre tty flip rewrite) kernels.

2009-03-24usblp: continuously poll for statusPete Zaitcev
The usblp in 2.6.18 polled for status regardless if we actually needed it. At some point I dropped it, to save the batteries if nothing else. As it turned out, printers exist (e.g. Canon BJC-3000) that need prodding this way or else they stop. This patch restores the old behaviour. If you want to save battery, don't leave jobs in the print queue. I tested this on my printers by printing and examining usbmon traces to make sure status is being requested and printers continue to print. Tuomas Jäntti verified the fix on BJC-3000.

2009-01-27USB: usblp.c: add USBLP_QUIRK_BIDIR to Brother HL-1440Brandon Philips
My Brother HL-1440 would print one document before CUPS would stop printing with the error "Printer not connected; will retry in 30 seconds...". I traced this down to the CUPS usb backend getting an EIO out of usblp on the IOCNR_GET_DEVICE_ID IOCTL. Adding the USBLP_QUIRK_BIDIR fixes the problem but is it the right solution? output from strace /usr/lib/cups/backend/usb after printing a document (Note: SNDCTL_DSP_SYNC == IOCNR_GET_DEVICE_ID): before patch open("/dev/usb/lp0", O_RDWR|O_EXCL) = 3 ioctl(3, SNDCTL_DSP_SYNC, 0x7fff2478cef0) = -1 EIO (Input/output error) after patch open("/dev/usb/lp0", O_RDWR|O_EXCL) = 3 ioctl(3, SNDCTL_DSP_SYNC, 0x7fffb8d474c0) = 0 Possibly related bug: https://bugs.launchpad.net/ubuntu/+source/cupsys/+bug/35638 Signed-off-by: Brandon Philips <bphilips@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-01-27USB: CDC-ACM quirk for MTK GPSAndrew Lunn
This patch adds a device quirk for a MediaTek Inc GPS chipset. The device implements USB CDC ACM, but is missing the union descriptor, so the ACM class driver fails to probe the device.

2009-01-07USB: Enhance usage of pm_message_tAlan Stern
This patch (as1177) modifies the USB core suspend and resume routines. The resume functions now will take a pm_message_t argument, so they will know what sort of resume is occurring. The new argument is also passed to the port suspend/resume and bus suspend/resume routines (although they don't use it for anything but debugging). In addition, special pm_message_t values are used for user-initiated, device-initiated (i.e., remote wakeup), and automatic suspend/resume. By testing these values, drivers can tell whether or not a particular suspend was an autosuspend. Unfortunately, they can't do the same for resumes -- not until the pm_message_t argument is also passed to the drivers' resume methods. That will require a bigger change. IMO, the whole Power Management framework should have been set up this way in the first place. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2008-08-13usb: cdc-acm: drain writes on closeDavid Brownell
Add a mechanism to let the write queue drain naturally before closing the TTY, rather than always losing that data. There is a timeout, so it can't wait too long. Provide missing locking inside acm_wb_is_avail(); it matters more now. Note, this presumes an earlier patch was applied, removing a call to this routine where the lock was held. Slightly improved diagnostics on write URB completion, so we can tell when a write URB gets killed and, if so, how much data it wrote first ... and so that I/O path is normally silent (and can't much change timings).

2008-08-13usb: cdc-acm: stop dropping tx buffersDavid Brownell
The "increase cdc-acm write throughput" patch left in place two now-obsolete mechanisms, either of which can make the cdc-acm driver drop TX data (nasty!). This patch removes them: - The write_ready flag ... if an URB and buffer were found, they can (and should!) always be used. - TX path acm_wb_is_used() ... used when the buffer was just allocated, so that check is pointless.

Fix bogus assignment of "unsigned char *" to "char *": preserve unsignedness.
